Method to separate articles and an apparatus to supply separated articles

A star index wheel with a plurality of semi-circular notches furnishes round or cylindrical articles to a supply index wheel of the automatic machine at an rate coinciding with the spacing of the semi-circular notches in the supply index wheel. The star index wheel is disposed on the side of a carrying conveyor on which the round or cylindrical articles are transported without any gaps between them. The star index wheel rotates at a speed whereby the semi-circular notches move at a speed slightly less than that of the linear speed of the carrying conveyor, so that the movement of the articles on the carrying conveyor is constrained by the protrusions provided between the semi-circular notches in the star index wheel. The rotational speed of the star index wheel also separates the articles to synchronize the rate at which they are supplied to the supply index wheel with the rotational speed of the supply index wheel.
